Jedes IP-Paket wird unabhängig an sein Ziel vermittelt (geroutet) und der Pfad dabei nicht aufgezeichnet. Andere Internetprotokolle wie IPX wurden von IP weitgehend verdrängt. 4 Transportschicht Die Transportschicht (englisch: Transport Layer) ermöglicht den Transport von Segmenten zwischen Prozessen auf unterschiedlichen Geräten über sog. Ende-zu-Ende-Protokolle. Beim Sender verpackt die Transportschicht die Daten der Anwendungsschicht in Segmente. Beim Empfänger erkennt die Transportschicht die Segmente in den Paketen der Vermittlungsschicht.
